MACHINE FOR COLORING OR COATING PAPER OR LIKE MATERIAL.

SPECIFICATION forming part of Letters Patent No. 557,056, dated March24, 1896.

Application led June Z9, 1895. Serial No. 554,428. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, LOUIS DEJONGE, Jr., of Stapletomin the county ofRichmond and State of New York, have invented certain new and ImprovedMachines for Coloring or Coating Paper or Like Material, of which thefollowing is a full, clear, and exact description.

My invention relates to a machine for coloring or coating paper and likematerial, and the prime object of the invention is to improve upon theconstruction of the machine for which Letters Patent were granted to meFebruary 5, 1895, No. 533,443, and afford a means whereby provision maybe made on the cylinder of the machine for sheets of any size, theadjustment of the bed receiving the sheets being expeditiously andconveniently made.

Another object of the invention is to perfect the construction of thegripper-s of the machine adapted to hold the paper on the bed.

A further object of this invention is to simplify the devices forelevating` the paper and holding the same in position until caught bythe clips carried by the drying-machine usually used in connection withthe coloring and coating machine, and otherwise to simplify theconstruction of the patented machine.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fullyset forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional view through the cylinder adapted to carry thepaper. Fig. 2 is a front elevation of the said cylinder, illustratingits construction in detail. Fig. 3 is a front elevation of the liftingbar or plate carried by the cylinder. Fig. 4 is a plan view of a sectionof the bed adapted to receive the paper and adapted to have suctionapplied thereto. Fig. 5 is alongitudinal section taken substantially onthe line 5 5 of Fig. 4. Fig. (5 is a side elevation of what may betermed the lower7 section of the paper-receiving bed. Fig. 7 is avertical section of a portion of the bed and a lifting plate or bar.Fig. 8 is a similar view taken at another point through the liftingplate or bar. Fig. 9 is a detail sectional view of a portion of thecylinder, illustra-ting the position of the gripping devices andlifting-bar at the time of receiving the paper from the feed-table ofthe machine. Fig. .lO is an end view of the cylinder, illustrating theposition of the grippers just preparatory to receiving the paper fromthe feedtable, the trip devices being in section, the said section beingtaken practically on the line 10 10 of Fig. 11. Fig. 11 is a sideelevation of that end of the cylinder shown in Fig. lO. Fig. 12 is anend view of the cylinder, -illu stratin g the position of the partsconnected therewith at the time of taking the paper from the feed-table.Fig. 13 is a view similar to Fig. 12, illustrating the position of theparts at the time when the grippers are about to release the paper. Fig.14 is an end view of the cylinder, as shown in Figs. 12 and 13,illustrating the main gripping device as released from the paper and thelifting-plate elevated to permit the clips upon the dryingmachine tograsp the paper. tional view through the cylinder with the parts inposition as shown in Fig. 14. Fig. 16 is a sectional view through thecylinder, illustrating the manner in which suction is applied to the bedreceiving the paper and also illustrating the release of both the mainand auxiliary grippers and one in which the clips from thedrying-machine may grasp the paper. Fig. 17 is a view of the oppositeend of the cylinder to that shown in the other figures and illustratesthe manner in which the auxiliary grippers are released and carried tothe position shown in Fig. 16 and Fig. 18 is a View similar to Fig. 17,in which the actuating device for the auxiliary grippers is shown in aposition to apply the auxiliary grippers in clamping position on thepaper.

ln carrying out the invention the cylinder A of the machine, which inthe form shown forms the support for the bed adapted to' carry thepaper, consists principally of two heads 20, which are secured to aconnecting-shaft 2l, the said shaft being provided with an interiorchamber 22 for a portion of its length. The cylinder may be revolved inany suitable or approved manner, and ordinarily one of Fig. 15 is a see-IOO its heads is provided with a gear a, which meshes with a smallergear a on a drivingshaft a2, mounted in a suitable frame A.

The cylinder is adapted to carry a bed B, upon which the sheets to becolored or coated are placed and held. rlhis bed maybe shortened orlengthened according to the size of the sheet to be operated upon, andthe said bed preferably consists of a series of plates of twoconstructions, one construction of the plate being designated as 23 andthe otheras 24. The plate 23 is provided with a central rib 23l upon itsunder face, extendingnearly to the ends, whereby it is substantially T-shaped in cross-section, and the ends, which are carried over the heads2O of the cylinder, are provided with openings 25, through which screwsor other fastening devices4 may be passed. The plate-sections 24 of thesaid bed (shown in Figs. 4 and 5) are provided with ribs 24n on theirunder faces, starting from a point near their ends and terminating ateach side of the center, connectin gwith a box or a chamber 24b formedupon the bottom of the plate, the upper surface of the `plate havingapertures 26 made therein o`ver`the aforesaid chamber, and each chamber24b of the bed is fitted with a nipple 27, by means of which thesechambers may be connected by tubes 2S with the tubular portion 22 of thecylinder-shaft 21, the said tubular section of the shaft being connectedwith an exhaust-fan or its equivalent. These plaie-sections of the bedare placed with their sides in contact with each other, as shown in Fig.l, and the box-sections are placed near the ends of the bed and at acentral point, so that when suction is applied to the box-sections thepaper will be drawn down upon the bed and held at its ends and at itscenter, and it is obvious that byadding or taking away sections of thisbed it maybe lengthened or shortened, as occasion may demand.

It is necessary that the cylinder should be balanced, and therefore arms29 are placed upon the cylinder-shaft 2l, usually one at each side ofthe center, and these arms ca rry a weight 30 at theirfrce ends, thesaid ends being provided with slots 3l to receive adjusting-screws 32passed through said slots and into the weight, Fig. 2, andadjusting-screws 33 are used to secure the arms 29 on thecylinder-shaft, Fig. l. Under this construction it will be observed thatthe arms may be adjusted on the shaft and the weight adjusted on thearms in a manner to counterbalanee the bed formed on the cylinder. 1nany event, however, the weighted arms must center` the bed, as shown inFig. l.

In connection with the bed a lifting bar or plate C is provided, and4this lifting bar or plate may be shorter than the space between theheads of the cylinder or of substantially equal length, and the plate,as shown in Fig. 3, is provided at each side of its center withelongated transverse openings 34 and with recesses 35 in its upper edge,the said recesses being adapted to permit the passage of the clips 35carried by the sockets 35b of the machine B, Fig. 16, adapted for dryingthe paper after the said paper has been coated or colored on the machineforming the subject-matter of this specification.

The lifting-plate C is attached to what may be termed the lower sectionof the cylinderbed B, which is a T-shaped section 23, and is shown inFig. G. In making the attachment angle-irons 3G are bolted or otherwisesecured to the under face of the said bed-section in advance of itsiiange 23, as shown in Figs. 7 and 8, and bolts 37 are passed throughthe slots 34 in the lifting-plate and into the said angle irons orbrackets 3G, as is particularly shown in Fig. '7, so that thelifting-plate is capable of vertical movement or movement outwardly andinwardly from the cylinder.

The flange O03 he of the aforesaid lower bedsection is also providedwith angle-brackets 3S, the lower members whereof extend outwardly fromthe cylinder, as shown in Figs. G, '7 and S, and these brackets arepreferably placed between the angle irons or brackets 30, which arepreferably attached to the plate proper. The angle-brackets 3S extenddownward well below the angled irons 3G and below the lower edge of theliftingplate C when the latter is iu its lowermost position. Rods 39 aresecured to the lower edge of the lifting-plate and extend downwardthrough openings in the angle-brackets 38, terminating at their lowerends in heads 40, and a spring 4l is coiled around each of the rods 30,having bearing against the head of the rod and the bracket, while studs42 are formed upon the lower end of the lifting-bar outside of thespring-controlled rods, as illustrated in Figs. 3 and 7.

A shaft 43 is journaled in the cylinder A below the receiving end of thebed B, as shown in Figs. l and 2. The shaft 43 is provided with fingers44 contained within the cylinder and preferably adj ustably located onthe shaft, and these fingers are adapted for engagement with the lugs 42on the lifting-plate C, being especially adapted to elevate the saidplate in order to permit the clips 35 of the drying-machine to grasp thepaper at the recesses 35 in the said lifting-plate. The shaft 43 extendsbeyond the left-hand head of the cylinder and carries at said end anangle arm or cam 45, as shown in Figs. 2, l0 and ll.

Just before the receiving end of the bed arrives at the point at whichthe sheet is to be discharged and just before the sheet is released fromthe clamping mechanism used the angle arm or cam is brought in contactwith the stud 4G projected inwardly from the extension of the frame A',located at the lefthand end of the cylinder, as shown in Fig. 1l. As thecylinder revolves, the angle arm or cam in passin g the stud will rockthe fingershaft 43 in .a manner to force the lingers against the lugs 42of the lifting-bar C and lOO will carry the said bar up to the .positionshown in Figs. 14, 15, and 16, thereby elevating the sheet, and, asheretofore stated, permitting the clips of the drying-machine to readilygrasp the edge of the paper, as illus- A trated in Fig. 16, and justafter this gripping action has taken place the cam will be released fromthe stud 46, as is particularly shown in Fig. 14, whereupon the fingers44 will drop downward and the lifting-plate will be restored to itsnormal position through the medium of the springs 41 connected with theplate and placed under tension when the plate is lifted.

A main gripper or clamp is employed to hold the advance end of the paperon the bed B,and in addition auxiliary grippers or clamps are also used.The main gripperor clamp (shown best in Figs. 1 and 2) consists of aplate 47 curved in cross-section and made to extend over the liftingplate or bar to an engagement transversely with a sheet of paper 4S.This plate contacts through out its length with a sheet of paper, as isshown in Fig. 2, and is located at the central portion of the receivingend of the bed, and in addition to this plate extensions or side plates47 f are used, located at each end of the main plate 47, in order thatthis main gripper or clamp may be given any desired length. The clampsor grippers are removably and adj ustably attached to a shaft 50, whichis journaled in the heads of a cylinder Aat a point between thelifting-bar and the finger-shaft 43, and a pinion 5l is securedpreferably to the lefthand end of the shaft, as is likewise shown inFig. 2.

The pinion 51 meshes with a second pinion 52 secured on the inner orright-hand end of a short shaft 53, journaled in bearings located at theleft-hand cylinder-head, as illustrated in Figs. 10, 11, 12, and 13. Theleft-hand end of the shaft 53 extends some distance beyond thecylinder-head, as shown in Fig. 11, being securely fastened to thecentral portion of the cross-head 54, having forked or bifurcatedextremities, designated respectively as 54a and 54D. The cross-head maybe termed a shifting-head, as it is employed to effect a change in theposition of the main clamping plate or plates.

One end of a rod 55 is eccentrically and pivotally connected with theshifting crosshead, the attachment being made near one side edge betweenthe connection of the head with its shaft 53 and one of the forks-thefork 54, for example. At the opposite end of the rod 55 and intermediateof its ends the rod is held to slide in bearings 56, located upon theleft-hand head of the cylinder, and a spring 57 encircles the rodbetween its upper bearing and a collar 58 contained upon the rod, thespring being so attached to the rod as to cause the latter to exertconstant pressure upon the shifting cross-head in an outward direction.

The shifting cross-head assumes two positions, both tangential to thecylinder. In one position the fork 54b is the outer one and in thesecond position the fork 54a assumes that place. In the first-namedposition of the shifting cross-head the clamp is opened, as shown inFigs. 10, 14 and 15, and held away from the sheet-receiving bed B,allowing the sheet to be removed or another sheet placed in position tobe clamped, and in the second position of the shifting cross-head theclamp will hold the sheet upon the said bed firmly and securely. Thetension-rod 55 acts to hold the shifting cross-head in either position.

The shifting cross-head 54 is acted upon by two studs 59 and 60, securedto extensions formed at the left-hand end of the frame A',

one of the studs-the upper one, (S0-being located at the upper portionof the said frame extension upon a bracket 60, projected npwardtherefrom, and the otherstud is placed near the lower end of theextension, as is best shown in Fig. 1l. The lower stud, 59, is in thevicinity of a feed-table D, as shown in Figs. l0 and 12, the upper stud,60, being located adjacent to that point at which the sheets after beingcolored are to be caught by the clips of the drying-machine, or wherethe said sheets are to be otherwise removed from the cylinder. Bothstuds extend horizontally from the aforesaid frame extensions indirection of the left-hand head of the cylinder.

In the operation of the clamp 47, supposing the clamp to be in the openposition shown in Figs. 1 and 10, which figures represent the cylindernearly ready to receive the sheet D' of material to be coated, the stud59 will at that time have entered the fork 54@L of the shiftingcross-head. As the cylinder revolves in the direction of the arrow, Fig.10, the inner fork, 54, or that engaged by the xed stud 59, will becarried forward, and the shifting-pinion 52 will be turned in adirection to so move the clamping pinion 51 that the clamping-plate 47will be forced upon the sheet D' if the latter is fed to the receivingend of the bed B, as shown in Fig. 12. The closing of the clamp takesplace when the fork 54a of the shifting-head is the outer one, takng theposition formerly occupied by the fork 54h, the cross-head having beenturned practically end for end, and in this movement of the shiftingcross-head the tension-rod will be thrown to the opposite side of thecenter of the said shifting-head, and will therefore hold the head inits changed position. The shifting cross-head will remain in theposition shown in Fig. 12, causing the clamping-plate to hold the sheetuntil the sheet has received its coloring compound or coating, and alsountil the point is reached where the sheet is to be removed from thecylinder. At this time the sheet is released from the clamp by the upperstud, 60, entering the fork 54h, which in the revolution of the cylinderwill be the forward one, as shown in Fig. 13. As the stud G0 acts uponthe fork 54b by the revolution of the cylinder, the

IOO

shifting-head is rocked or rotated until the fork 54b is brought to theupper position and the fork 54 to the lower position, (shown in Fig.14,) and the clamping-shaft 50 is therefore rocked in a direction toremove the clamp from the sheet, this position of the shiftingheadcorresponding practically to its position at starting, as shown in Fig.10.

As the cylinder continues to revolve it carries the bed B downward toreceive another sheet, the said bed facing the front of the machine, andwhen the receiving end of the bed approaches the feed-table D the sheetwill be fed out to the bed in any approved manner, or as shown anddescribed inthe patent heretofore alluded to, and about the 4time thatthe contact is made between the receiving end of the bed and the sheetto be colored the lower stud, 59, will have acted upon the shiftingcross-head in such a manner as to reverse the same and close the clampagainst the sheet. Thus another sheet is in position to be acted upon orcoated and to be released at the upper portion of the machine orWherever the releasing trip-stud may be located.

As heretofore stated, auxiliary grippers or clamps are employed inconnection with the main clamp 47. These auxiliary clamps cousist ofhook-shaped bars 61, adjustably located on a shaft G2, journaled insuitable bearings 63 secured upon the outer face of the lifting plate orbar C, as shown in Fig. 3. The auxiliary clamps are placed one at eachend of the main clamp, as shown in Fig. 2, and are adapted to extendover the upper edge of the lifting-plate to engage with the advancededge of the paper while on the bed B.

It is obvious that the auxiliary clamps move with the lifting-plate, andtherefore recesses 64 are made in the heads of the cylinder to permitvertical movement of the clamp-shaft. These auxiliary clamps are adaptedto hold the paper on the bed of the cylinder after the main clamp hasbeen removed from the bed and while the lifting-bar is in its outerposition, the auxiliary clamps being so placed as not to interfere withthe movement of the withdrawingclips 35L when employed, and theseauxiliary clamps release the sheet of paper simultaneously with itsbeing engaged bythe aforesaid clips. This is accomplished preferably bysecuring upon the right-hand end of the shaft G2 a cam 65, (shown inFigs. 17 and 18,) being at the right-hand end of the cylinder. This camis of elongated shape and is provided with a head 67 at its outer end,which extends beyond the upper face of the bed B, and a smaller head 6Gat its inner end; and at the forward side of the cam, nearer its outerthan its inner end, a lug 68 is formed, the said lug serving as a meansfor attachment to the clamp-shaft 62.

A rod G9 is pivotally attached to the cam near its inner head and at therear of and out of alignment with the point of the attachment of the camto its shaft.

The rod 69 has play at its inner end in a bracket 7 0, secured upon theouter face of the right-hand cylinderhead, and a spring 7l is coiledaround the rod having bearing upon this bracket and likewise against acollar 72, formed on the rod.

The inner head of the cam is adapted to be engaged by a trip-pin 7 3,extending horizontally inward from the extension of the frame A at theright-hand side of the cylinder, and this pin is located nearly oppositethe point where the paper sheet is to be withdrawn from the bed; and asecond trip, 74, preferably in the nature of an arm, issecured to themain frame A', as shown best in Fig. 1, slightly in advance of thefeed-table near the point where the paper sheet is to be received uponand clamped to the cylinder-bed.

In the operation of the machine the main and auxiliary clamps are openedout from the bed and the lifting-bar is in its inner position when thebed of the cylinder approaches the feed-table. At the time that thesheet D to be coated is fed to the receiving end of the bed B the mainclamp 47 is closed upon the sheet throughv the medium of the lowertrippin, 59, operating the shifting-head 54 in the manner heretoforedescribed, and at practically the same moment that the clamping of themain clamp is eected the outer head of the cam will have struck thetrip-arm 74, and the said head will' be drawn back wit-hin theperipheral line of the cylinder-head, as shown in Fig. 18, and thespring-controlled rod 69 will have been carried over the center of thecam, holding it in this itsv inner position, and the cam in assumingthis position will so rock the shaft 62 as to carry the auxiliary clampsto a bearing on the paper also.

The paper is now carried in contact with the distributing-roller of anyapproved form of color-applying device E, and the color is distributedon the paper by means of brushes F, arranged around the rear of thecylinder, or other approved means. Then the advanced end of the bed Bapproaches the point where the paper is to be removed, the upper trip,60, at the left-hand side of the cylinder will operate upon theshifting-head in a manner to release the paper from the main clamp 47,and as soon as this release is eifected the finger-shaft 43 will beoperated from the lefthand trip-stud, 4G, through the medium of its cam45, and the fingers 44 will force the lifting-bar C outward, raising thesheet at the advanced end of the bed, the auxiliary clamps meanwhileholding the sheet in place on the bar, and at the time the sheet is tobe removed either by machinery or by hand the inner head, G6, of the camG5 will be acted upon by the upper right-hand trip, 73, and thrown tothe position shown in Fig. 17, substantially the reverse of that shownin Fig. 18, and the auxiliary clamps are then removed from contact withthe paper and the spring-controlled rod G9 will hold the cam 65 in thisits outer or IOO IOS

open position until it is again brought to the vicinity of thefeed-table to clamp another sheet.
